This example attempts to create a bucket called 'hello-world' and, as the bucket hello-world has already been created by someone else in S3's global namespace, throws the following exception. Change 'hello-world' to something else to avoid the exception by creating a uniquely named bucket. The new...

In other cases, List.fold is the function that is best suited to calculate such a sum.
Sum of complex numbers
In this example, we declare a list of complex numbers and we calcu...

In order to remove a S3 bucket, you must first remove all of the S3 objects that are stored inside of the bucket, provided you have permission to do so. In the above example, we are retriev...
This will be our example data frame:
df = pd.DataFrame({"color": ['red', 'blue', 'red', 'blue']},
index=[True, False, True, False])
color
True red
False blue
True red
False blue
Accessing with .loc
df.loc[True]
color
True red
True red
...
This will be our example data frame:
color name size
0 red rose big
1 blue violet big
2 red tulip small
3 blue harebell small
Using the magic __getitem__ or [] accessor. Giving it a list of True and False of the same length as the dataframe will give you:

Let's consider this example, that outputs the squares of the numbers 3, 5, and 7:
let nums = [3, 5, 7]
let squares = nums.map(function (n) {
return n * n
})
console.log(squares)
Run in RunKit
The function passed to .map can also be written as arrow function by removing the function keywor...

Each watchOS target includes an App and an Extension. App contains the UI stuff and Extension contains the actual logic (similar to Views and Models in MVC architecture in iOS).
Each WatchKit App has a Interface.storyboard file which you design the app in it, and a Assets.xcassets file to put your ...
Consider a company where every employee who is a manager, manages 1 or more employees, and every employee has only 1 manager.
This results in two tables:
EMPLOYEES
EMP_IDFIRST_NAMELAST_NAMEMGR_IDE01JohnnyAppleseedM02E02ErinMacklemoreM01E03ColbyPaperworkM03E04RonSonswanM01

SELECT e.emp_id , e.first_name , e.last_name FROM employees e INNER JOIN managers m ON m.mgr_id = e.mgr_id WHERE m.mgr_id = 'M01' ;
Results in:
EMP_IDFIRST_NAMELAST_NAMEE02ErinMacklemoreE04RonSonswan
Ultimately, for every manager we query for, we will see 1 or more employees returned.
Consult the above example tables when looking at this example.
SELECT m.mgr_id , m.first_name , m.last_name FROM managers m INNER JOIN employees e ON e.mgr_id = m.mgr_id WHERE e.emp_id = 'E03' ;
MGR_IDFIRST_NAMELAST_NAMEM03BarrelJones
As this is the inverse of the above example, we know that for ...
